Patented March 5, 1907.

1 Application filed October 21, 1904. Serial N 'o. 229,442.

To alt whom, it may concern:

Be it known that I, JAMES B. HAMMOND, a citizen of the United States, residing at New York city, New York, have invented certain new and useful Improvements in Type- Writers, of which the following is a specification.

The machine relates to that type known as the Hammond.

In my present form of machine I have sought to so arrange. and proportion the arts that the anvil and shuttle may be of arger size than have heretofore been used in this type of machine in order'that a larger number of characters may be used on the shuttle than has heretofore been possible.

The invention consists in the features and combination and arrangement of parts hereinafter' described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the machine with parts omittedand'parts shown diagrammatically for clearness of illustration. Fig. 2 is a sectional view of the machine from front to rear with some parts shown in elevation. Fig. 3 is a detail view'showing the means for operating and controlling the ribbon-spool on the opposite side of the machine from that, illustrated ih Fig. 2. ing from the rear of the machine of the means for controlling and operating the ribbon-feed pawls'and detent. Fig. 5 is a detail View of one of the detents of Fig. 6 is a detail cross-sectional view of the frame for the ribbon. Fig.7 is a sectional view along one of the axes of one of the ribbon-spools. Fig. 8 is a detail view relating to the ribbon-spools.

In these drawings, 1 indicates the anvil,

- and 2 the shuttle carrying the type characters.

The impression is made upon the paper through an inking-ribbon.(indicated at 3nby means of a hammer, (not shown, butw 'ch is well known in thistype of machine.) The ribbon passes along a shield 4, across the face of the shuttle, and its ends are wound upon ribbon-spools5, which in my present inven-. tion are arranged to turn on the horizontallydis'posed axis lying in a direction transversely of the machine, so that the ribbonspools lie at each side of the center frame and turn in vertical planes passing from front to rear of the machine.

- Fig. 4 is a detail view look-' the ribbon-movement:

ribbon-spool on the opposite side of the ma- The arrangement of parts and the proportions are such that Ican employ in my present machine an anvil of large diameter, and consequently the shuttle may be of larger size, presenting a greater surface area for the location thereon of a large number of characters in the same or different languages. .The ribbon-spools are driven through toothed wheels 6.

Referring. to Fig. 2, it will be seen that the toothed wheel belongin to the ribbon-spool at the left of the mac 'ne, Fig. 1, is operated by a pawl 7, carried by a lever or arm8, which is fixed to a shaft 9. This shaft is journaled in the center framework 10 of the machine. This shaft is provided with an arm 11, fixed thereon, with which is connect ed a rod .12, extending downwardly and bearingupon a part of the universal space-frame 13, so that each time one of the character keys is operated the space-frame will cause the operation of the .rod 12, and thereby the operation of the pawl 7 through the rockshaft 9 and arm 8, .and this pawl e a the toothed wheel connected with the ribbonspool will move the same .step by step as the keys are struck. In order to hold the ribbon-spool in moved position, a detent 14 is provided, pivoted on a shaft 15, journaled in the machine-frame, the said detent being arranged in the same vertical plane with and below the pawl 7 to engage the teeth of the wheel 6.

h Fig. 3 shows the means for operating the 9O chine, or, in other words, at theright of Fig. 1, and this Fig. 3 represents the positions of the pawl and detent in respect to the toothed wheel at the right of the machine at the time that the pawl and detent at the left of the 5 machine, as shown in Fig. 2, are in active engagement with the toothed wheel on that side of the machine. The pawl for the righthand side of the machine (indicated at 16) is v pivoted to an arm 8, which, like the arm 8 I00 above mentioned, is fixed to the rook-shaft 9,

so that as the rock-shaft moves forward thepawl is operated in the direction .of the toothed wheel and will turn the same when it is in engagement therewith. Fig. 3, how- 10 5 ever, shows the pawl held out of e age ment, and this is accomplished through its detent 14, which is held in its uppermost or raised position by means of a cam-shaped collar 18 on the shaft 15, said collar having a I 1 cut-out portion 19 and a high portion 20. withbent ends 41, passing beneath the wire. 65
